nobody is mocking people in the first place.
I'm not sure why you are invoking people with disability. Disabilty is ripe for mockery it deserves it. It's a way of dealing with it. I know from close up.
What is being mocked is the fairy tales that some people believe.
I used disability for no reason other than it was there. I could just have easily have chosen any from a number of other 'groups' (although I don't like grouping people).
I'm not disabled and so I don't think it would be appropriate for me to mock anyone else's disability. How people with disabilities deal with their situation is entirely up to them.
At least you agree that faith is being mocked on here anyway.
